The APRS Working Group is currently reviewing and is
generally in favor of a number of the common revisions,
updates and additions that have accumulated since the
original release of the APRS1.0 spec. These items and
others have been accumulated over the years on the
APRS SPEC errata page:
http://www.ew.usna.edu/~bruninga/aprs/errata.html
Now, a non-controversial subset has been specifically
identified for publication as a spec 1.1 Adendum. After
thirty days the working group will formally vote to adopt them.
